This study investigates the Failure Modes, Effects and Criticality Analysis (FMECA) Method for the railroad vehicle. Recently, RAMS (Reliability, Availability, Maintainability and Safety) is one of the most important issues in the railroad industry. FMECA is prerequisite for the RAMS Analysis, and it is a procedure to identify the potential failure modes and their effects and to reduce or mitigate the critical effects on the system. FMECA is used in various industries and it is specialized in each industry. For instance, MIL-1629a and SAE-J1739 are specialized FMECA method for Military industry and Automotive industry, respectively. Although the railroad industry requires the high reliability system, it does not have a specialized FMECA yet. Thus, in this paper, an FMECA method specialized to the railroad vehicle was proposed through analyses and comparison of the MIL-1629a, SAE-J1739 and IEC-60812 standards.

As the opening of Korea Railroad Express on April 1, 2004, it has extended the transportation capacity of railroad, and decreased the time and moving cost. Railroad Express is industry composed of transportation, advanced technology, and grand project for synthetic plan. Hence, here now, as the anniversary of Railroad Express, we should analyze the overall effect of Korean Economy by KTX. relationship with other industry, social and cultural change. That is the key point what is the change during the year and how we catch the chance to develope the Korea Railroad for the national economy. The KTX has overcome the speed which the traditional railroad not been. But the Express has a weakness in searching of customer or goods. KTX is helped by electronics and telecommunications. so we need to find new industry in relation to KTX. And we should have open mind and vision for international railroad.

This study discusses how the appropriate distribution and logistic information system of the railroad industry will be developed when the Korean railroad will be open toward northeast Asia area through South Korea and China/Russia in the rail-ferry project and/or the inter-Korean railroad connection project in the fnture. This study suggests that the Korea railroad industry should build the own efficient information system of railroad distribution and logistics in the notheast Asia area far both the extension of customer services and the competition with peripheral countries around the pacific.

Korean railway has run about 110 years since 1989 and played a great role of industrialization in Korea. It is known that rail transport systems have many advantages of being more safe, energy-efficient, and environment-friendly, as compared to other transportation systems. However, railway incidents are often attributed to the failure of safety management and critical to the efficiency of railroad industry. This study reviewed economic, financial, and general statistical information on Korea Railroad. Based on the statistical data, the effect of accidents on railroad management was analyzed. Correlation analysis revealed that railway accident had a negative effect on the gross profit of Korea Railroad. In order to reduce potential risks and incident rate, some recommendations are proposed. Actual or potential applications of this research include safety guidelines for improving efficiency of railroad industry.

Recently, the Korean government has been making efforts to achieve 'creative economy' based on science and technology. As part of these efforts, it has been promoted specific policies for innovation and performance enhancement of national R&D projects. They contains commercialization of research outcomes, technology transfer, technology based startup and support small and medium-sized businesses. The railroad transportation industry is a representative in the field of SOC and has own characteristics different from other industry areas. Especially, industry and market of railroad transportation are directly related to planning and implementation of government SOC policies. So in order to promoting commercialization of railroad transportation projects, it is very important to ensure consistency between government policies and R&D projects. In this paper, we investigate barriers of successful commercialization with typical researchers in the area of railroad transportation, and suggest problems and improvements of policy-based commercialization by giving specific examples.

By Chinese growth, economic development and investment of the West-coast are consisting. Specially, the West-coast area need tourist development and tourism Import for the Incheon and the Pyeongtaekhang of the Gyeonggido Province, China trade through the Chungcheongdo Province area. According to such regional special quality, the railroad tourism industry should be activated. Sunset of tourism infra in the West-coast is high value as representative goods of the West coast. Development of the theme railroad tourism industry that utilize the tide may maximize regional advantage of China and capital region. This research is basis investigation to examine development possibility as sunset theme railroad tourism industry of the West-coast.

Present Prices have reduced to $100 per barrel, but international oil prices caused big damage to local logistics industry due to rise in International oil prices and, in august 2008 oil prices reached up to 146 US. Depending on oil prices, the domestic logistic industry should develop a strategy by innovative management of purchase of supply for manufacturing industry and efficient supply and demand of resources which is believed to be more important. Accordingly, we want to analyze railroad logistics' present condition and effect on railroad industry that can expect affirmative development by oil-price rise and by developing strategies for efficient railroad logistics.
